Product Overview

The LT1506CS8-3.3#PBF is a monolithic buck mode Switching Regulator functionally identical to the LT1374 but optimized for lower input voltage applications. It will operate over a 4 to 15V input range compared with 5.5 to 25V for the LT1374. A 4.5A switch is included on the die along with all the necessary oscillator, control and logic circuitry. High switching frequency allows a considerable reduction in the size of external components. The topology is current mode for fast transient response and good loop stability. Both fixed output voltage and adjustable parts are available. A special high speed bipolar process and new design techniques achieve high efficiency at high switching frequency. Efficiency is maintained over a wide output current range by keeping quiescent supply current to 4mA and by utilizing a supply boost capacitor to saturate the power switch.
  • Easily synchronizable
  • Uses all surface mount components
  • Cycle-by-cycle current limiting
  • Inductor size reduced to 1.8µH
  • 0.07R Saturating switch design
  • 20µA Shutdown current
